WidgetParams

Service useful for setting a default JSON value to your widget. It is used by the Widget Mixin.
You just have to add an entry to the MappedConfiguration parameter. The first value is
the name of the widget, then the second one is the JSON Object.
With this functionnality, you do not have to specify for each widget the JSON parameter. By default,
it will take the one defined with this service. If both of them are defined, Tapestry-jQuery will merge
them.
It is also used by the customDatepicker and customZone mixins.
